To all whom t may concern/.a

Beit known thatl, GUSTAVUS A. HERZOG, a

citizen of the United States, residing at San Francisco, in the'connty of San Francisco and Stateof California, have invented certain new and yusefull'm provernents in Machines for ImitatingWood-Surfaces,of which the following My invention` relates to painting-macl1ines,

and more particularly to amachine for imi The object ofmy inven 'on is to produce a,

simple and easily-operated 4Inachine forV the purpose, so'constrncted as to give better resultsV and more nearly perfect reproductions `than ,has beenheretofore possible.

` to receive the bottom sills B of the movable. structure B, which supports the painting ap` `My machine is represented in the accom-V panying drawings, in which-` Figure 1 is a plan View. Fig.' 2 is a sectional elevation on line Fig. 1. Fig. 3 is a side elevation. Fig. 4. is a rear elevation. Fig. 5 is a longitudinal section on line g] 'y of l Fig. 1.

A represents the base of the machine, ywhich 1s a long narrow trough having side guides 1 1 parat'us. Rollers 2 are journaled in sills B. The structure B is a Aframe t having upright side guides 44 for the roller-frame C, which is movablevertically insaid guides and carries the transferring-roller D, whose shaft projects through between the side guides and is'provided with a crank 6. The rollerand its carrying-frame are suspended from a shaft or windlass 7, havingaorank 8 and journaled in the frame B atthe top and on which is wound a rope, which is made fast to the cross'- head 9 of the roller-frame. The roller is surfaced with any suitable soft or yielding cornposition adapted to retain a colored pattern and to transfer the same.

At one end of the structure B and hinged thereto above the base is a spreader E, which can be turned down on itshinges from the in.- cective position shown in the drawings to a vertical position in which -its edge is nearly in contact with the bottom. Occupying a substantially similar position, but preferably vat the other end of the frame B, is a hinged scraper F, which is usually made of soleleather and which can be raisedk or lowered the main transferring-roller is journale'dra blending-brush G, the brushfhead 1l of which can be turned so as 'ro raise and lower the said brush respectively out` of contacta-nd into contact with the bottom. r

a In operatingthe Inachinethe model-.boardl H, which isgenerally apieceof hard wood f withadcsirable grain, is placed on thebot` i tom, abutting against yan'intermedfiate'diviy sion-strip 12, and anotherboard-I, Onwhich" thegrain isto be imitated, is .set on Lth'e'oth'er side. of said strip. This lastboardfis'usually' of soft wood,,such;as` pineorv redwood'. The

vsurface of the modelaboardis charged with a suitable oilc'olor yin front `of. theflow'ered spreaderE, the brush-G andthe impressionroller'being-bothraised, aswellas the scraper.

The frame B is now pushed back over the board H, (to the right in Figf1.) Thefspre'ader will charger-he whole'width of the modei- Y' board with the color. kThe spreader is now raised and the wiping-scraper F lowered, the frame being moved` so far back that the scraper is inline with the` end ofthe surface ofcolor.

The traveling frame is now'pushed in the oppositedirectiomthe scraper wipingsSo fthe surface clean of any surplus of colon-'but leaving-- a thin lilm on ,the board. When j enough of the cleared surface appears, the im-V pression-roller isloweredand rests uponthe Y board. The frame and roller, the latter revolvin gby frictional contact,are now pushed steadily forward up to the other end of the scraped board, andthe scraper and roller areraised to pass the dividing-strip.l Theroller now carries on its soft cylindrical surface the accurate impression of the grain-marks ofthe model-board. The rollerv is nowlowered and also the blending-brush, which follows it..

This blending-brush is one of the m'ost im- I. y

The frame is pushed over the soft-Wood board to the extreme end of the table, the roller transferring the imitation to its surface.

At the front end of the base is a tank K, containing benzene for cleaning the roller and blending-brush, the traveling frame being pushed to that end and the brush andthe roller revolved in the contents of the tank.

It will be observed that the roller, scraper, spreader, and blending-brush are all carried by the same traveling structure, and, further, that the modehboard and plain board can both be placed in the machine at the same time and at different ends, so that it is not necessary to set or adjust the plain board after the design has been taken by the roller. This enables the Work to be performed more rapidly.

Having thus fully described my invention, what I claim as new, and desire lo secure by Letters Patent, is-

l. In a machine for imitating wood-surfaces, the combination with the traveling roller for receiving a design from one board and transferring it to another, of a blendingbrush mounted so as to follow the said roller in its transferringr operation.

2. In a machine for imitating wood -surfaces the combination of a base, a traveling structure mounted thereon, a roller suspended and revoluble in said structure and an adjustable blending-brush also mounted in said traveling structure.

In a machine for imitating wood-surfaces, the combination of a base, a traveling structure mounted thereon, a roller-frame vertically movable in said traveling structure and carrying a roller, a spreader hinged to the traveling structure and a scraper also hin ged thereto.

4. In a machine for imitating Wood-sun faces, the combination of a base, a traveling structure mounted thereon, a roller-frame vertically movable in said traveling structure and carrying a roller, a spreader hinged to the traveling structure, a scraper also hinged thereto and a blending-brush.

5. In a machine for imitating Wood-surfaces, a trough-like base having guides, and provided with seats for supporting two boards simultaneously and upon substantially the same plane, a frame, a structure movable in said guides, and an adjustable roller, an adj ustable spreader and an adjustable scraper all carried by said movable structure.

In testimony whereof I have affixed my signature, in presence of two witnesses, this 13th day of February, 1902.
